Graphene is a two-dimensional material consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It has revolutionized the field of materials science by becoming one of the most promising materials for electronic devices, energy storage, and biomedical applications due to its unique properties.
(what makes graphene a good conductor)
One of the main reasons why graphene is considered a good conductor is that it has a high surface area-to-volume ratio, which means that there are more atoms per unit volume on the surface of graphene compared to other materials. This allows for more efficient movement of electrons across the surface, resulting in faster electrical conductivity.
Another important factor that contributes to graphene’s excellent conductivity is its high thermal conductivity. Graphene has an intrinsic temperature coefficient of resistance of -34.7 °C·K^-1, which means that it can transfer heat quickly without losing significant power. This makes it particularly useful in applications where temperature control is critical, such as in high-temperature electronics or in semiconductor manufacturing.
In addition to these physical properties, graphene also exhibits some unique electronic properties. For example, it has a non-trivial band structure, meaning that it has multiple bands of different energies that can be manipulated independently. This allows for the creation of new types of electronic circuits and devices using graphene, such as integrated circuits and photonic devices.

Overall, the combination of high surface area-to-volume ratio, high thermal conductivity, and unique electronic properties make graphene a highly desirable material for use as a conductor. As researchers continue to study graphene’s properties and develop new applications, we can expect to see even more exciting developments in this field.
